Analysis :: Convert Tabular Model To Multidimensional
Sep 25, 2015
We have a requirement to convert Tabular model to Multidimensional as few functionalists like actions does not support in tabular. Looking for list of things needs to take care to convert tabular solution to Multidimensional.
How to correctly open Multidimensional Model in SSAS to Excel Power View Report? I am continuously getting this error message when open with Power View Report.
"Sorry, something went wrong while loading the model for the item or data source 'PC01-4300095 Sales Cube'. Verify that the connection information is correct and that you have permissions to access the data source."
Is it possible to have Analysis Services in both modes or are they mutually exclusive?I have a machine setup with Multidimensional AS and would like to know if it's possible to add a Service in Tabular mode.
I have a Tabular model, it has 8 tables , 7 of the tables process in 3 mins, but the main table is 22.3gb in size//I am processing the table on a 64 bit pc with 8 gb ram to the local instance from a Production server//At this rate it will take days to process the Main table 22.3gb, the main table was running off a view but I have inserted the data into TableA and updated the model///Only other optimization process I can think of is copying TableA to my local machine but the performance to the Server on the network is not an issue.I am just process the main table for the last 4 hrs and it is only at 11.7 mill records out of 124 mill total @ this rate it will take 44 hours
I have been looking at implementing a tabular model based on an OLTP database that's not dimensional. I know that this is possible but during my proof of concept I have encountered numerous problems ...
The things that I have run into are: After setting up the relationships I have found that measures filter context don't propagate along the relationships as I would expect. if the measure is coming from a target table and not a source then an ALL member is returned ( as in multi dimensional when a dimension isn't related to a measure group). Given the lay out of an OLTP database this will be hard to avoid.
One thing I have done to try an mitigate the above problem is to combine the tables used for measures in a view and using that in the source to connect to the rest of the tables. however due to the tables being of different grains this has then created duplication in some of the keys and measures. so the keys cant be used in relationships and the measures aren't accurate.
Are these things other people have come across? or should I give up the ghost and just recommend using dimensional models for the source? is tabular just geared towards a DW the same as multidimensional?
I created a model in Visual Studio 2012 and when I process the model, most tables (the ones that should) process 77,546 records and that is reflected in VS.
However, when I deploy the model to the server it is only deploying 76,500 records for those tables.
Where those 1,046 records went to? Is there a setting that limits the records to be deployed? My base tables in the Data Mart have 77,546 records, just as in my Visual Studio model.
I get the following error while processing a SSAS tabular model (2014) on a new server.The SSAS service on this server is running under a login which has access to the SQL server data sources. I tried changing the provider to OLEDB from SQLCLNI11 in the connection string but that doesn't work too. The error message isn't useful to debug further.
The cube processing succeeds on a different server. I scripted out the cube DB and ran it on the new server and am trying to process full but it fails with the following error.
Error Message: The operation failed because the source database does not exist, the source table does not exist, or because you do not have access to the data source.

We are working on implementing DAX formula(s) on our tabular model (SSAS 2012). When we tried to deploy the solution, deployment wizard giving us then below error:The given key was not present in the dictionary...I checked all the formula(s) that we recently implemented and all looks fine.
I'm working on a Tabular model at my job since the users have a requirement to query against a live data source. I've been looking online for clients that issue DAX as opposed to MDX to the model, but besides SSRS and Power View, I could not find anything else. Any other client side interfaces to a DirectQuery Tabular model?
I built my first tabular model and see that my fact tables are also appearing as dimensions. In Multi dimensional mode i could choose which are the dimensions. How do i do that in tabular model.
I have a separate date dimension marked as Date table in Tabular Model and having proper relationship with another table(e.g SalesTable) with column of date type. But still time intelligence functions are not working. I am using the date column from other table (e.g SalesTable) in the formula. What exactly going wrong in our tabular model.
I have only 1 denormalized table that is being used in a SSAS Tabular model(which is about 3GB). I am doing a POC to convert it into a SSAS Multidimensional and explore it.
1st Question) I am seeing that there is no Primary Key(unique key) in the current denormalized table. (Tabular Model didnt require any primary key). But i think for Multidimensional the key is mandatory? Should i generate a composite key myself in a Named Query based on this table(in the DSV)?
2nd Question) What is the best way to design my Multidimensional Cube/Dimensions based on this single table?
Say if i comeup with a Composite Primary Key called (PK_ID) . Should i be splitting up my facts / dimensions in my DSV using Named Queries similar to below(Using the same PK for my dimension tables also?)
a) FactTable = Select PK_ID, Qty1,Cost1,Price1,Amount1 from Table1 b) StoreDim = Select PK_ID, StoreName,StoreDese from Table1 c) ItemDim = Select PK_ID, ItemName,ItemDesc from Table1
I have created one Multidimensional CUBE, while browsing(Analyze in Excel) it in Excel, I am unable to create TimeLine Slicer.It is giving me following error as: "We can't create Timeline for this report because it doesn't have field formatted as Date".
I have Dim_Date having Date as a column of Day level granularity. In PowerPivot, we do mark Dim_Date Table as a 'Date Table'.In the same way, do we have to set anything here so that Excel will come to the Date format for TimeLine Slicer?
I am trying to implement data masking based on user login and not sure why this is not working. I have the dimensions DimBrand, DimProduct and DimUser. I should mask the BrandCode with 'XXXX' nothing but in the report all the BrandCode should appear but few of the code will be masked if the user is not belongs to that group. I have a fact table FactProduct in this. In the cube I created all these 3 dimensions and the fact table. I created a new dimension DimBrandMask and I separated the code over there with a relationship with the actual DimBrand dimension. In the cube a reference relationship is set up with the measure group. Created a role with read access.
In the dimension data tab of role I put the below MDX to allowed set.
I have a question about partitions in both SQL Server table and Tabular Model. I started to use Tabular Model recently.
I need to partition a table that collects daily rows for different clients.
The natural partition key is a combination of clientID+dateID (something like CL-YYYYMMDD)
I created a configuration table with a primary key PartitionID IDENTITY(1,1) , that contains also the field clientID and dateID
Every day I add a new row in it and I get a partitionID for the new client and date
Then I created a partitioned fact table using PartitionID as the partition field, using the partition function and the partition schema as well.
The daily client data is inserted in the partitioned table using the partitionID
Everything works fine, and the data are loaded correctly into the partitioned fact table.
Then I created a Tabular Model where the fact table is the partitioned table, and I created tabular model partitions using something like "select <field list> from PartitionedTable where partitionID = <partitionID>"
In this way, every day I load partitioned data in both sql server and tabular model. I have two dimensions, client and calendar
Now my question is: when I browse the Tabular Model, and I'm selecting a specific dimension date and dimension client, am I using the partitionID index correctly?
Or should I put in the tabular model partition query something like "select <field list> from PartitionedTable where clientID = <clientID> and dateID = <dateID>"? In this case is still working the partitionID index? How can I check it?
I am trying to learn building SSAS tabular model. While following a tutorial I need to add a column to an existing table but for some reason the ADD Column option (insert column in other menu is also not appearing) is greyed out.
i have a model contains fact of account revenue , a time dimension and scd of account.
the scd (type 2) is changing when an account get a new color.
when i queries the model by PowerPivot i sometimes get wrong color for an account in a date priod , for example , I would expect to see color 3 for account 1 at 04-06-2010 , But instead I see color 1 - as you can see in the picture bellow.
FACT , SCD :
Result
i process all , deploy , mark dim_time as date dim , and i still cant find the error.
I have been living in the T-SQL world for years, and am working on my first Tabular model.
I have a fact table that I would like to use for many reports. My idea is that I would use Perspectives in the tabular model to pull in the columns that I need for each purpose. In some cases, I also need to filter out some rows. Is there a way to filter perspectives? The only solution I am coming up with is to create views in SQL Server and import the fact table multiple times for each purpose. That doesn't seem very efficient.
My boss and I attended the SQL conference in Vegas a few years ago. He remembers a session on tabular where the presenter said when the underlying table that tabular is built on changes, it automatically refreshes the tabular db. Now that we're working on a tabular project I'm looking around for this information and don't find anything like that happens. From what I can see, the refresh either has to be scheduled from a task, or manually refreshed by right-clicking the db and selecting "process db". He said the session presenter was a Microsoft Program Manager too. Is there any truth to what he remembers?
According to the book "Microsoft SQL Server 2012 Analysis Services - The BISM Tabular Model" (pages 276 and 277) the following DAX query should work. However, I'll get a rank of 1 returned for every product name. My impression is that ALL doesn't block the context transition for product name. Because there is nothing in the errata, I might do something wrong!? The second query is just a workaround giving the correct result.
SQL 2014...In SSDT, as I'm developing my tabular model I often add new columns to the underlying table/view that feeds my model. When I go into Table/Table Properties, select the new column I've added then hit OK it spins and spins then times out. My model has just over 1 million records. The only way I can get it to work is to delete the table and then add it in again.
how to combine measures and fields coming from an analytical model (tabular) along with some Excel calculations. Basically I want to provide users with a simple report (to be displayed in SharePoint Excel services) containing charts and slicers. The data comes from a tabular model, and most of the calculations are in the model as well.However there is some little tweaking that must be done. For example I might need additional calculated columns, but I don't feel the need to modify the tabular model for that. I was wondering if I could do this within Excel as well -- but without having to bring all the data through a pivot table, then manipulate it and then show it on the report. So to be clear I do not want any pivot tables lying around, even if on a hidden sheet.
I noticed that when selecting a pivot chart in Excel, at the ribbon menu under "PIVOTCHART TOOLS"/"ANALYSE" there is a group of buttons named "Calculations". One of them is named OLAP Tools.Is it fair to assume that these options will allow me to create new measures at the Excel side, without affecting my tabular model?
What I want to do is be able to show a measure that SUMS the number of hours logged by anyone who is a SiteManager from the ConstructionSites table.
I wanted to do a SUMX of WorkerTimesheets against HoursLogged, but FILTER against WorkerTimesheets[WorkerID] = ConstructionSites[SiteManagerID] so only workers who are also SiteManager would be counted.However, I can't seem to get that to resolve it always throws an error along the lines that it can't determine context.
SQL Server Data Tools within VS 2010 Shell.2012 SASS in Tabular Mode.I've created a Measure and KPI in my fact table. I've created a perspective named "Summary" When selecting the fields and measures for display in the perspective, the measure is available, but not the KPI (target, status, etc.). When Analyzing in Excel with the Summary perspective, the KPI is not available in the field list. When analyzing in Excel with the (default) perspective, the KPI is available.As far as I can tell, there is no way to select a KPI within the perspective window.
getting a complete Microsoft DW/BI (Tabular), Power BI and Office enviroment up running. I am a (Microsoft) DW/BI manager and want to learn about the latest Microsoft DW/BI (SQL Server Tabular) and Power BI (Power Pivot, Power View, ...). To save time & access from anywhere, I thought I could use Windows Azure but quickly got lost in the Azure preview and market place! I even contacted the Windows Azure team and that didn't clarify things.
So, how to get a SQL Server (2014) environment with all DW/BI (SSIS, SSAS, SSRS, Data Mining) technologies together with Power BI and Excel working? If so, how to get started.If this is not possible on Azure and it has to be done on Window, what do I need to install for the Power BI stuff (to work with Tabular)? I already have SQL Server 2014 and Office Pro Plus installed natively on my Windows machine.
I have a new 2014 SSAS installation. During VS2013 Tabular Project create I get an error Cannot connect, Reason The workspace database on server ***** is not running in tabular mode.I've changed msmdsrv.ini - DeploymentMode>2...The server wont start.
I am working with SSAS Tabular. I have a stand alone table with 60 columns and contains 120K records. Table size is 250MB. And trying to build a tabular report out of it and it is taking longer and throwing exception, screenshot attached.
It might be cross-join issues, as workaround created a dummy measure and using in report. But it working for 10-20 k records and beyond throwing same exception. I have 8 GB RAM and 100 GB free disk space.
i would like to pose a question, when a user do a login in SSRS server,is it possible to pass the username to SSAS tabular, to implement security? I've tested using USERNAME() creating a role that relates USERNAME() with a dim user username, but now i need to implement it with the username used in SSRS server.
I have a Tabular data model and I'm returning a measure that counts employees (each row is an employee) and then a calculated column in the model that gets SeniorityInMonths.
So if an employee was hired exactly 1 year ago, they would have 12 in this column.
I want to group these into bins, but the Group option is grayed out.
